I'm probably not thinking this through all the way, but wouldn't a memory profiler be more straight-forward, and less dangerous in Smalltalk?
I haven't built one myself, but I know that the Seaside framework comes with a built-in memory profiler.
Doing intercession of messages to objects in Smalltalk isn't trivial, but it isn't voodoo either. I whipped up a quick method replacement class that swaps out a database 'save' method's behavior for testing. However, I would imagine that trying to replace VM primitive calls would lead to some not-so-nice side effects (maybe... or would it just make the image slower?).
I like Ruby, and I like Smalltalk, but I'm liking Smalltalk much better lately because the "turtles all the way down" aspect which makes things like a memory profiler much less "voodoo-y".
- tptacek 17y agoReplace "memory profiler" with any other piece of runtime manipulation, and the point is just as valid with Smalltalk. It is not, in fact, "turtles all the way down"; eventually you hit the ABI, and that's what this article is talking about.
